This document I have, did not solve an issue directly, it describes
possible solutions depending on your infrastructure and requirements.****
** **
Such documents are not very usefull for end customers this should be the
part for your Enterasys Partner, you should report him your problems and he
have to find a possible solution that may fit to your infrastructure and
requirements not Enterasys. It’s just like a workshop manual for a car. It
does’nt help you to fix your issue in all possible cases, thats the same
like this document. ****
** **
It would NOT fix your problem. I only want to give you a hint that there
exists a fix exist for a different infrastructure and you have to open a
case at Enterasys‘ GTAC to solve your issue or to contact your Enterasys
Partner.****
** **
The Partners are there to have an overview whats on the market and whats
are the possible issues with your infrastructure and your requirements.***

Hi Adam,****
****
For the Microsoft NLB: The cluster NEVER talks with his virtual MAC
address. *You should put in the cluster members in a seperate vlan and
assign the virtual MAC address to this vlan*, but I am not sure if the B5
supports this. Our customers core switches are N-Serie’s there you can
configure this.****
****
Please could you explain this point, I mean, is there any article or
document about it?****
****
Thanks****

Hi****
****
We had the same problem with one of our customers with his Microsoft NLB.
****
****
In which configuration does your NLB Cluster work? Unicast? Multicast?****
****
For the Microsoft NLB: The cluster NEVER talks with his virtual MAC
address. You should put in the cluster members in a seperate vlan and
assign the virtual MAC address to this vlan, but I am not sure if the B5
supports this. Our customers core switches are N-Serie’s there you can
configure this.****

Hi all,****
****
Sometime ago I made some questions about configuring a B5G stack to work
against a NLB cluster from TMG, only switching (Thanks Sylvain, Markus and
everyone who helps me).****
Now I have to enable routing on that B5G so, of course, I have another
problem.****
I’m configuring static routes. If I put as gateway to a network the
virtual ip (VIP) of the NLB latency grows incredibly, so performance is
quite poor.****
I’m forced to config as gateway the dedicated IP of one of the NLB nodes,
disabling NLB on the other machine.****
This is the routing config:****
****
!****
ip route 10.1.0.0 255.255.0.0 192.168.7.3****
!****
interface vlan 20****
ip address 192.168.7.10 255.255.255.0****
no shutdown****
interface vlan 200****
ip address 192.168.249.254 255.255.255.0****
no shutdown****
!****
arp 192.168.7.1 03BF.C0A8.0701****
!****
****
On the switching side I have “set mac multicast” config pointing to ports
where TMG servers are connected.****
****
Thanks****
